If you're seriously interested, look into a work visa. I fucked up and only went for 3 weeks. Next time I go, it'll be for six months. Incredibly easy to get a job when you're passing through town, and they pay about 25 AU dollars (which is pretty good man). Room at a hostels $20. You could realistically go there broke. I plan to go with a few grand to buy a van, and thats all bud. You can totally do it
